He called me an "a**hole"?

Sounds to me like you are taking it way too seriously. He's probably just joking around. Where I'm from, at least, people call each other names sarcastically all the time. It isn't meant to be taken seriously, especially if you were being sarcastic first (in this case, you were). I know it's a harsh fact, but profanity and name calling is everywhere in the world. You have to just let it go, it not a big deal.
